Irradiation is used in diagnostic imaging, cancer therapy and blood transfusion. In 2011 researchers found that irradiation was successful in the novel theranostic technique involving co-treatment with heptamethine dyes to elucidate tumor cells and attenuate their growth with minimal side effects.
Water is potable when it is safe for drinking by humans and other animals. Rainwater and even seawater can be processed into potable drinking water at a water filtration plant. Minute amounts of bleach can be added to water to purify it. Campers might use purification tablets to make small amounts of potable water.
Water is a very complex substance and its unique properties are essential for life. Its physical properties shape the hydrosphere and are an essential part of the water cycle and climate. Its thermodynamic properties determine evaporation and the thermal gradient in the atmosphere.
